' To allvwhom it mag concern:-

-Be it known that I, Sutton NAGER, Jr., a citizenof' the United States, and a resident andStateofNewYork, have invented a new and Improved Automatic Tape-Strip Printof which the following is a full, clear, and exact description.

My invention relates to a device for printing, moistening and cutting automatically, strips of tape unwound from a gummed roll of tape.

An object of the invention is to provide a' simple, strong, compact, inexpensive and automatic machine, which is neat in appearance, which is easy to manipulate and in which rolls of gummed tape can be easily and quickly interchanged.

Another object of the invention is to provide a tape printing and moistening device in which the strip of tape delivered, can be picked up without touching the moistened, gummed surface of the strip.

I A further object of the invention is to provide a device in which tape of different widths can be used, without any alteration or changes in the device.

With-the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combinat1on and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of the views, and Figure 1 is a longitudinal vertical section of my device; Fig. 2 is a trans verse section on the line 22, Fig. 1; Fig. 3 is a horizontal section on the line 3-3, Fig. 1 ;'Fig. 4-is a fragmentary view of the stripcarryingmechanism, showing the same at the moment of cutting off the strip; Fig. 5 is a similar view, showing the strip-cutting mechanism in a different position; and Fig.

6 is a diagrammatic view, showing the printing mechanism in a different position from that shown in the preceding fi ures.

- Referring to the drawings, represents a base of any suitable material, to which is rigidly secured, a frame 8, the side 9 of which extends above the oth er side 10 of the frame. Mounted in the upper central part of the side 9, is a fixed axle 11, to which a spider 12 is attached adjacent the side 9.

Another sp1der13 is removably attached to the axle 11 at the free end thereof. Be-

tween the spiders 12 and 13, a roll of tape 14 is mounted on the axle 11, and in accord ance'with'the width of the tapeused, the

distance between the spiders 12 and 13 will Y mounted on the said-axle 11. The roller 15 t is preferably flanged-at one end, to guide the tape 16 coming from the roll 14; about said roller 15, back to the roll 14:. 4

C0-acting with the roller 15, is a printing roller 17, for which the roller 15 forms a support. The said printing roller is removably'associated with the ends of a pair of pivotal arms 18, the other end of each of said arms 18 being engaged by a bolt 19,

pivotally connected to a resilient member 20' attached to the base. The resilient members 20 permit a variation of pressure on the rollers 15, by the printing roller 17 through the medium of the bolts 19.

Mounted between the sides of the frame adjacent the printing roller, is an inking device, consisting of an ink-transferring roller 21, in contact with the printing roller 17 and an ink-carrying roller 22. Another roller 23 contacts with the ink-carrying roller to uniformly distribute on the outer surface thereof, the ink passing from the inside of the ink-carrying roller to the outside thereof. All of said rollers are mounted in facing slots 21, provided in the frame sides 9 and 10. Said slots are'so' formed, that gravity maintains said rollers of the inking device in contact with each other and the printing roller 17. To prevent an excessive pressure by said rollers of the inking device on the printing roller, adjusting screws 25 are provided in the lower part of the slots,

which are in engagement with the bearings of the lower roller axle, that is, of the ink printlng roller 17 becomes impressed by the printing roller 1'7.v The so im ressed tape 1s then passed again over t e roll 14, threaded through a guide 27, from where it is passed between the feed roller 28 and the roller 29, co-acting therewith.

The feeding roller 28 has -a part of its peripheral surface 30 rendered inactive by depressing the same, so that only a part of its periphery will feed. The length of this feeding surface of the feeding roller 28, is equal to the length of strips which the device is adapted to dispense. The feeding roller 28 is driven positively through a train of gears, of which a gear 31 is associated withthe feeding roller 28 and which gear 31 is in mesh with an idler 32, meshing in turn with a gear 33, constrained to rotate with a drive shaft 34, a crank or handle 35 being attached to the shaft 34 for actuating the same, and therewith all other parts of the device.

A sprocket 36 is provided to turn with the shaft 34. An endless chain 37 connects the sprocket, 36 with a sprocket 38, which sprocket is mounted to turn on a stud 39, mounted in the upper part of the frame side 9. Mounted to turn with the sprocket 38 is a gear 40, in mesh with a similar gear 41, rotatively mounted on a second stud 42. Mounted to turn with the gear 41 is a sprocket 43. The stud 42 extends across the frame and mounted to swing thereon. is an arm 44, which is central With the plane of the roll 14. The arm 44 carries'a feeding roller 45, which is mounted to turn in the free end of the arm and preferably has an indented surface, so as to grip the tape. The feeding roller 45 has associated therewith, a sprocket 46 connected by an endless chain 47 with the sprocket 43. The feeding roller 45 is maintained against the tape roll 14, by a resilient member 48 mounted on the stud 42 and as the diameter of the roller decreases, the arm 44 is moved toward the axle 11. Although the diameter of the roll of tape decreases, the amount fed from the roll by the feeding roller 45 will be con-- stant, in View of the fact that the same will travel the same length through each revolution of the driving shaft 34. The ratio of the sprockets constituting the constant feed, is such that a length of 5% inches is dispensed from the tape roll during each revolution of the crank or handle 35. The length of the effective lateral surface of the feed roller 28, is also equal to 5% inches. The train of gears from the drive shaft to the feed roller 28, is such that the feed roller feeds faster than the feeding roller 45, for the reason that the said feeding roller feeds constantly, while the feeding roller 28 feeds intermittently and consequently, to feed the same length, the intermittent feeds must be faster.

By providing an intermittent feed, the tape can be severed in strips during the time the feed of the tape is arrested. The length of strips severed by the cutting mechanism,

will be equal to the effective feeding surface of the feeding roller 28. The cutting mechanism is of a guillotine type, consisting of a blade. 49, mounted to slide in grooves, pro vided in the frame sides 9 and 10. A sup-- port 50 also mounted between the frame sides, is adapted to co-act with the blade 49, which is maintained above the support against a stop 51, by means of spring-actuated plungers 52 carried by the frame sides. The blade 49 carries a roller 53, which contacts with a cam 54, mounted on the drive shaft 34, and whereby said blade is depressed against the support once duringeach revolution.

The tape coming from the intermittent feed to the cutting mechanism, is first passed through a guide 55 positioned betweenthe feeding and cutting mechanism and in alinement with the support 50, so as to cause the tape coming from the intermittent feed, to slide over the support. Positioned in front of the support and bearing in the frame sides 9 and 10, is a moistening roller 56, which is partly immersed in water, provided in a receptacle 57 resting on the base 7. The moistening roller 56 is geared to the feed roller 28, so as to rotate in the same direction as the feed roller. A pressure roller 58 is provided on the top of the moistening roller, to maintain the gummed side of the tape against the moistening roller. A baflie plate 59 is also provided above the support 50 and between the support and the moistening roller, so as to direct the tape over the support to the moistening roller. During the cutting of the tape by the blade 49, the moistening roller 56 slips over the gummed side of the tape contacting therewith, but as soon as the tape is severed, the same is moved forward by the turning movement of the moistening roller.

The strips of tape coming from the moistening roller, fall on a delivery table or support 60, the length of which support, is less than the length of the strip severed from the tape, so that a' portion of the severed strip 61, extends beyond the support 60 and can be bent as indicated in the dotted lines in Fig. 1 and ,thus be picked up from the support without the fingers contacting with the moistened, gummed side of the strip and. without bringing any portion of the moistened, gummed surface of the strips into contact. The so picked up strip of gummed paper or tape, which carries the desired parts, without necessitating the removal of the casing.

In Fig. 6 a modified structure of the device is shown. In this figure, the printing roller 17 is located above the co-acting roller 15. The constant feed mechanism is not shown. When the roll of paper 14 has its gummed side unexposed, the winding of the tape 16' is shown in full lines in Fig. 6, and when the gummed side of the tape roll 14 is exposed, the winding of the tape 16", would be such as shown in dotted lines in the same figure.

From the above description, it will be seen that my device comprises a support for a roll of tape, from which the tape is fed to a printing mechanism, the feeding of the tape from the roll being obtained by a constant feed mechanism toward an intermittent feed mechanism, the two mechanisms being adapted to feed a predetermined, constant length of tape. Clo-acting with the intermittent feed mechanism, is a strip-cutting mechanism, which is adapted to support the tape at the time when the intermittent feed is not feeding the tape toward the cutting mechanism. The severed strips from the cutting mechanism, pass over the moistening roller and from there to a delivery table, from which they can be picked up by engaging the non-gummed side of the severed strips.

From the foregoing description, taken in connection with the accompanying drawings, the advantage of the construction and operation of the device shown, will be readily understood by those skilled in the art, to which the invention pertains and while I have described the principle of operation, together with the device, which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.
